Washington (CNN) -- Politics is serious business -- but not all of the time. From the halls of Congress to the campaign trail, there's always something that gets a laugh. Here are some of the things you might have missed:

Rough crowd

Former White House Chief of Staff Rahm Emanuel -- better known in some political quarters as "Rahmbo" -- found himself the target of an incoming egg during a stop Wednesday in Chicago's Little Village neighborhood, NBC Chicago reports. The egg missed Emanuel, who is expected to make an official announcement soon that he's running for mayor -- and the egg thrower remained unidentified, the TV station reported.

Not a fan

More trouble for Emanuel: His tenant Rob Halpin -- who reportedly refuses to move from a house he's been renting from Emanuel -- said he will run for mayor of the Windy City, according to a column by John Kass in the Chicago Tribune.

Halpin's refusal to leave could hurt Rahm's candidacy, too: "Now Emanuel's campaign is expected to be challenged in the courts, a legal maneuver backed by guys on the South Side who are part of the stop-Rahm movement," Kass wrote. "And Halpin's talk of candidacy highlights the argument that Rahm is not a resident."

Time to build an addition on the house perhaps?

'Real World' Rehoboth Beach?

Christine O'Donnell -- the Tea Party-backed Republican who came up short in Delaware's Senate race -- appeared Wednesday on the "Tonight Show With Jay Leno." Now that her schedule is free, O'Donnell said plenty of big opportunities are knocking on her door.

"The offers have been interesting," she told Leno. "Anything from a book deal to a reality show."

Notable quotable

"The Pentagon says it doesn't know who was responsible for launching a missile off the California coast. They don't know. Meanwhile Sasha and Malia [Obama] can't believe the awesome new video game they just found in the White House." -- Jimmy Fallon

From the Twitterverse

Rep. Peter Roskam, R-Illinois, tweeted during his trip to South Korea, where negotiations for a U.S.-South Korean free-trade agreement are under way. Roskam may be working on a difficult subject, but he took time out to rib President Obama on his love for the teleprompter:

In a new People magazine article, Sarah and Todd Palin shoot down tabloid rumors that they are on the verge of a $20 million divorce settlement.

"I call Todd on the cell phone [from the grocery checkout] and I say, 'Todd, you won't believe this cover!' And he says, 'Twenty million? Write me a check,' " Palin recounted to the magazine. "He's good about laughing some of that stuff off."

The picture you need to see

Someone missed his mark.

In this Getty Images photo, the caption notes, "Obama is moved to the correct spot by South Korean President Lee Myung-Bak and his wife, Kim Yoon-Ok, for a photo during the official reception ahead of the G20 Working Dinner on November 11, 2010, at the National Museum of Korea in Seoul."

Stephen Colbert: "Things are terrible right now so they [congressional Republicans] are planning to make some bold changes. Yes -- extending the existing tax cuts will create jobs. Because the only way out of this mess is to keep things exactly as they are."

Conan O'Brien: "President George W. Bush has not been in the news for a long time. The day I come back on the air after a 10-month absence he returns -- with a book."

Jay Leno: "While in Indonesia, President Obama said he is making progress toward ending people's misunderstanding about Muslims -- like the fact that he isn't one."

David Letterman: "Bush says he's happy and spends a lot of time down there at his ranch in Texas. He's glad to be out of the Oval Office. And here's why he's glad to be out of the Oval Office: because he does not have to think all the time. And I'm thinking, 'Wait ... that was him thinking all the time?'"

Jon Stewart: "I can't believe that cutting through our national security bureaucracy to find out something that may not have actually happened [the mysterious rocketlike cloud in California] takes longer than an hourlong cable news shift."
